AGITATING' DEVICE FOR DIPPING-TANKS.

Specification Of Letters Patent.

Patented Apr. 11, 191.6.

Application filed October 4, 1915. Serial No. 53,894.

To all whom t may concern.'

Be it known that CHARLES TJ'CARLSON, arcitizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented a new and useful Agitating Device for Dipping-Tanks, of whichthe following is a specilication.

This invention relates to agitating devices and has more especialreference to an agitating device adapted to be located within the usualdipping tank which is employed in the manufacture of enamel ware, andcontains the enamel in a liquidV form, into whichl the articles to becoated are dipped. The form of dipping tanks at present in use for thispurpose is not provided with any agitating Vmeans and since the enamelused contains a great quantity of powdered material such as silica andmetallic oxids, there isa tendency' for these powdered materials tosettle to the bottom of the tank, leaving the mixture iny the upper partof the tank too thin and it isk necessary to frequently stir or agitatethe mixture by hand in orderto procure a uniform coating of enamel uponall of the articles dipped therein.

The Object of the present invention is to provide a dipping tank with anagitating deviceby means of which the enamel contained in the tank iscontinuously agitated, a uniform consistency being maintained throughoutthe tank.

I A further object is the provision of a dipping'tank with a continuousagtating ldevice which will not interfere with the operation of thedipping.

A still further Object is the provision of a dipping tank provided witha continuous agitating device therein and ascreen arranged within saidtank to prevent the articles being dipped fromcoming into contact withsaid agitating device.

With these objects in view the invention consists in the novelconstruction and arrangement of parts, hereinafter described,illustrated in the `accompanying drawings, and particularly pointed outin the appended claims, it being understoodthat various changes in theform, proportions, size andminor details of construction may be madewithin the scope Of the appended claims, without departing from thespirit` or sacricing any of the advantages of the Y invention.

In the accompanying drawings:` Figure 1V is a vertical section through adipping tank provided with an agitating device. Fig. 2

1s a detail perspective view of the agitating device. Fig. 3 is asection on the line 3 3, Fig. 1. Fig. 4 is a fragmentary view of aportion of the tank.

Similar numerals of reference indicate corresponding parts throughoutthe several figures of the drawings.

0 Referring more especially to the construction illustrated in theaccompanying drawings, the numeral 1 indicates the dipping tank which ispreferably formed of sheet metal, cylindrical in shape, the upper edgeof the side wall of said tank being provided with a bead 2 upon whichrests the outwardly disposed flange 3 of the annular member 4, saidannularmember being'prosoy located inthe 'bottom of the dipping tank, Y

said shaft being provided with a pulley 13 by means of which power isapplied to the shaft.

The agitating dasher is mounted upon the upper extremity of the lshaft11 and comprises the disk. 14 around the periphery of which is providedthe up-turned annular flange 15. A ring 16, of substantially the@ samediameter as the flange 15, is spaced above said disk concentric thereto,andl connected byfmeans of the diagonally disposed strips 17 with saidflange 15, saidstrips be- L ing connected to the ring and flange by spotwelding, soldering, or other `suitable means. Each of the lstrips 17 isprovided with an out-turned flange or blade 18, preferably disposedatright angles to the strip. The diskV 14 is provided with a series ofradial slits having relatively short slits disposed at right angles toeach endthereofand the metal between these shorter slits is bent asshown in Fig. 2, forming down-turned scraper blades V19, arranged toscrape the bottom wall of the tank, agitating any of the heavier portionof the enamel whichl may settle thereon, and theup`-turned scraperblades 2O arranged to scrape the under-side of the screen, which will behereinafter described, dislodging any the agitator.

A series of diagonally located ribs 22a are formed upon the inner faceof the vertical wall of the tank, said ribs being diagonally disposed ina direction opposite to that of the blades 18 upon the agitator, saidblades arranged to co-act with the blades 18 upon the agitatorcontinuously agitating the enamel material within the tank. Acylindrical screen member 23a, formed of wire mesh or similar materialand provided with a bottom wall 24 is located within the tank as shownin Fig. l, the annular bead 25 formed upon the upper free edge of saidscreen resting upon the iii-turned annular flange 9 of the cylindricalportion 8 of the hopper, said screen being of a diameter slightly lessthan the inner diameter of the ring 1G and of a depth sufficient tobring the lower wall thereof into close proximity to the upturnedscraper blade Q0.

Vvlhen in use the tank is filled with the enameling material and theshaft ll continuously rotated, carrying therewith the agitating dasherabove described. rlhe diagonal blades 18 in combination with theoppositely disposed diagonal ribs 22a cause a continuously swirlingmotion of the enamel within the tank and as above described thedown-turned scraper blades 19 prevent the heavier portion of thematerial from settling to the bottom of the tank continuously agitatingthe material at the bottom of' the tank while the rip-turned scraperblades Q0 prevent any of the heavier portion of the enamel from adheringto the under side of the screen. rlhe articles desired to be coated withenamel are dipped within the screen member, said screen protecting thearticle being coated and the hands of the operator from coming intocontact with the rotary dasher.

l claim:

l. The combination with a dipping tank of cylindrical form, of acylindrical screen mounted within said tank and spaced from the side andbottom walls thereof and a ro-f tary agitating device located withinsaid dipping tank and-between said cylindrical. screen and the bottomand side walls of said dipping tank.

tank between said screen and the bottom wall of said tank, and upwardlyextending blades attached to the periphery of said disk and locatedbetween the side walls of said cylinder and said screen.

3. The combination with a dipping tank of the character described of arotatable agitating dasher provided with an open cento, and acylindrical screen located within said tank and extending within theopen center of said dasher.

el. The combination with a dipping tank of cylindrical form of aplurality of diagonally disposed ribs located around the inner surfaceof said tank, a disk rotatably mounted in the bottom of said tank, upvardly extending diagonal blades mounted upon said disk, said bladesdisposed at an angle to said ribs, means for continuously rotating saiddisk and a cylindrical screen mounted within said tank and extendingdownwardly between said blades.

5. rllhecombination with a dipping tank of cylindrical form, of aplurality of diagonally disposed ribs located around the inner surfaceof said tank, a disk rotatably mounted within said tank, upwardlyextending diagonal Vplates mounted upon said disk, a ring located at theupperextremities of said blades and connected thereto, means forrotating said disk, and a cylindrical screen mounted within said tankand extending downwardly within said ring.

6. rEhe combination with a dipping tank of cylindrical form, of avertical shaft extending through the'lower wall of said di aping tankand concentric therewith, a disk fixedly mounted upon the upperextremity of said shaft and spaced from the bottom wall of said tank,down-turned radially disposed scraper blades mounted upon the under sideof said disk, lip-turned radially disposed scraper bladesmounted uponthe upper side of said disk, an 1up-turned annular flange providedaround the periphery of said disk, upwardly extending scraper bladesconnected tov said flange, a ring located at the upper extremities ofsaid scraper blades and connected thereto and a. cylindrical screenmounted within said tank and extending downwardly within said ring, saidscreen provided with a bottom wall located adjacent'said Lip-turnedscraper blades,
